This specific error indicates that the openpyxl package, which is necessary for Pandas to read Excel files, is not installed on your system.

Why You Need openpyxl

Pandas uses openpyxl as an engine to handle Excel files (.xlsx). If you don’t have this package installed, Pandas will be unable to process the Excel files, resulting in the error you've encountered. It’s a common issue, especially for those new to data manipulation in Python.

How to Solve the Issue

Step 1: Install openpyxl

To fix the error, you need to install the missing package. Here’s how to do it:

Open your command prompt.

On Windows, you can do this by pressing Windows + R, typing cmd, and hitting Enter.

On Mac or Linux, simply open the terminal.

Run the installation command. Enter the following command into your command prompt or terminal:
